All good, it's totally normal in jams that you try to implement something and run out of time. Still, I genuinely loved the originality of the idea and the gameplay, it does look like you could expand it and make a full game out of this, you could take the route of the FTL roguelike, repairing the sub, maybe even fight another subs, maybe a map to explore the ocean... pretty cool idea with a lot of potential, well done!
